braska, have invented anew and useful Improvement in Door and Window Openings,

' of which the following is a specification.

Our invention relates to the building of door and'window opening in houses, more especially inschools and hospitals and the like, where neatness and freedom from dust and freedom from corners in which dust may gather are desideratums.

In the method now usually adopted, after the wall is up, a ground of cheap, soft wood is nailed about the edge of the opening left in the wall, the thickness of which is equal to the depth of the plaster which is ulti: matelyto line the wall. In fact one of the two main functions of-such a ground is to have its outer edge, away from the opening and away from the wall, to-acta'sa guide for the trowel which slicksor smooths the plaster into place. After the plaster has been applied to the wall flush with the ground, and has dried, the Windowcasingis put into placeand nailed down againstthe ground. This ond-function o acting as a support for the nails which secure the casing to thewall. There are then three sets of steps involved in the process of manufacture, the securing of the ground to the wall, the plastering, and the securing of the casing to the ground. Again the casing projects beyond the plaster, creating a recess or corner therebetween, in

which dust may lodge and from which dust. may only, with some difficulty, beremovedJ Then, too, it is quite difiicult to make a tight joint between the. casing and the. plaster so that the air and dust which may have filtered from theoutside between the wall and window frame may thence pass between (the frame and plaster into the room. In

our invention, we:substitute a two step proc ass of buildin "for the three step processabpve-descri d'j we producean opening, such" as atr"; window, in .which the edges'a re flush- 1 th the plaster, in which the ob ections abovfestated are overcome and in which the comparativelyexpensive door or window oasmg isrreplaced by a far cheaper length of narrow metal molding. In the drawings Figure 1 is a sectionab perspective of the present form of window structure; Fig. 21s a similar ,view of our imound thus exercises its sec-.

. metal surface proved window; Fig. 3' is a sectional perspective of the present style of door; Fig.-

each embodying our invention.

The wall A in the old style window, as

shown in Fig. 1, has secured thereto a weight box B having an outside stop B a staff bead B an inside stop B and a parting stop B between which two stops slides the window B To the weight box -B- is secured the guiding and nailing ground C. The plaster D, being applied and troweled flush with the outer'edge of the ground, is allowed to dry whereupon the casing E is nailed to the ground G and the window is finished. But, as we see, there is formed a troublesome corner F in which dirt may lie and from which it can only be removed with some diflicult-y. Besides the air which filters around between the wall and the parts attached thereto can gain ready entrance into the room through the joint formed by the casing E and the plaster in the corner F. This makes suchv and opening, in this case to. the side. of the weight box, a metal molding M constituted of a base flange M 'f0r nailing to the wall, a

projecting and preferably curved flange M sometimes making an angle therewith and, also preferably, a rent-rantflange M for locking the plaster. The moldinghaving been secured in place, it merely remains to apply the plaster flush with the outer edge M of the molding and to let it dry and the job is finished. It is thus seen that our molding acts as a guiding ground for applying the plaster, but" that the feature of having it act as a ground to which some-i thing is nailed is dispensed with. We note also that our plaster wall is smooth and unbroken by projecting casings right up to the window opening'so that there is pre-' sented a smaller number'of corners in which That the plaster and M, of Fig. 2 will stay cleaner-than the corresponding plaster and wood or metal surface .D, E, of Fig.1; and that it maybe more readily-cleaned when dust may lodg'g.

dirty, is obvious. We thus gain greater efficiency at less expense, for the molding M is not, only cheaper to manufacture than the corresponding casing E of Fig. 1, but it' is applied with one step less in the process of building, thus saving labor cost of installation. If the plaster wall D is painted then the aint is run to the angle between the parts I and M If the plaster wall is papered, then thepaper is run to a corresponding point. The projecting flange M of the molding M is, in fact, a flush co n' tinuation of the plaster wall surface around the window corner. i

In Fig.3 we have shown an old style door 7 opening in which the wall A has secured thereto a rough door ,frame A to which is nailed the finished door frame A which carries the door stop A and the door A. e again have a plaster guiding ground C, C, to which the door casing E is subsequently nailed. In our invention, however, as shown in Fig. 4, the wall A carries the rough door frame A the finished door frame A the door stop A and the door A.

But the nailing ground C and .casing E are dispensed with. Instead we use the same.

base flange M and the projecting flange M are'in line and not at an angle. This permits us to vary the thickness of the plaster coating.

It will thus or window opening which is supplied with the usual frame set within the opening and that we place, in juxtaposition to the frame,

the base flange of our molding, the projectbe seen that we take a door ing flange of which defines the thickness of the plaster coat. In this way we dispense with nailing grounds, we have the molding act'as a guide for the trowel in plastering, we do away with objectionable corners in which dirt may lodge and we substitute for' an expensive door or window casing a far a cheaper piece of narrow metal molding. When our invention is used on inset windows, as shown to the right-of Fig. 6, we may employ on the salient angle S, thus formed, any common form of corner head which, however, constitutes no part of our invention. I

We claim:

1. A wall having an opening; a frame the opening; a molding having a base flange in juxta osition to the frame and a projecting ange; and a -plaster coat on the Wall abutting against the molding, flush with its outer edge, which thus'acts as a substitute for the casing, substantially as described.

2. A wall having an opening; a frame in the opening; a molding having a base flange in juxtaposition to the frame and a curved projecting flange; and a plaster coat on the wall abutting against the molding, flush with its outer edge, which thus acts as. a substitute for the casing, substantially as described.

3. A wall having an opening; a frame in the opening; a molding having a base flange in juxtaposition to the frame, a projecting flange defining the thickness of the plaster and a rentrantfiange for locking the plaster; and a plaster coat 'on the wall abutting against the molding, flush with its outer edge, which thus ,acts asa substitute for the casing, substantially as described.

In testimony whereof, we have signed our names to this specification, in the presence of two subscribing witnesses.
